A beige Linhof ball socket tripod head. The bottom has a dial that can be turned if you unscrew the hand turnable screw at the side, along with a screw hole to attach a tripod into it. Above the dial are numbers, above that is a screw to unlock the ball joint in order to turn it around. the top of the joint has a flat round base and screw to attach it to something, probably a camera. A thread with a red seal is tied to the side screw.
